Hi, so I have one of those 13.5 EVO tanks and right now I have a yasha goby and a tiger pistol and one blue leg hermit, and I'm totally satisfied with just those guys if the tank is not big enough, but I was thinking of adding 2 more blue leg hermits, a porcelain crab, and 3 sexy shrimp. It's a euphyllia and mushroom dominated tank, so I have hammers and frogspawn in addition to discosoma and rhodactis and one yuma. I have some large (2.5ish inch diameter) rhodactis mushrooms that I want the sexy shrimp to host on, but I've read that they may prefer euphyllia and bother it. Will the porcelain crab host on the euphyllia? Do all porcelain crabs host? This is my first saltwater tank so I'm filled with questions. If they'll bother my yasha in any way I don't want them, she's very shy and wasn't bought at the pet store for several months because she never came out from under her rock while there were fish in the tank and people staring at her. Because of this I got her for $16.35 after tax so that's awesome. She's pretty confident now that she's left alone, so I don't want to ruin that. Any help would be greatly appreciated, mostly just wanting to know this is a good idea.
